BOSTON (AP) Tom Brady's missing Super Bowl jersey has been found in Mexico six weeks after it vanished from the Patriots' locker room - but the mystery isn't over.

The NFL said the jersey was found in "possession of a credentialed member of the international media," and authorities were investigating Monday whether a former Mexican tabloid newspaper executive played a role in the theft.

It wasn't the only piece of memorabilia recovered: Authorities found a Brady jersey that had gone missing after the Patriots' 2015 Super Bowl win over the Seattle Seahawks. A helmet belonging to a Denver Broncos player was also discovered, NFL spokesman Brian McCarthy said.

The missing jersey - and the subsequent investigation that stretched from Texas to Boston - captivated Patriots fans and social media for several days after the Patriots' 34-28 overtime win over the Atlanta Falcons.

"If it shows up on eBay or something, somebody let me know," Brady said after the game.

Houston police investigators relied on a tip from an informant to trace the jersey, estimated to be worth about $500,000, to Mexico.

U.S. and Mexican officials have not yet identified the suspect, but the name of a former newspaper director circulated widely in Mexican news media and on social networks. The newspaper's owner, Organizacion Editorial Mexicana, issued a statement saying the director had resigned from La Prensa on March 14 for "personal reasons." The company learned only Monday of his possible involvement in the Brady case, it said.

The paper said that if the accusations are true, it "strongly condemns" that the employee used his position "to obtain a media accreditation to be able to access the field of play, news conferences and probably other areas of NRG Stadium." It had not been contacted by investigators, the paper said.

A company official who was not authorized to discuss the matter publicly told The Associated Press on condition of anonymity that the former director was not part of the media outlet's Super Bowl coverage.

"He got accredited on behalf of La Prensa, but he took vacations. ... He was not sent by us," the person said. "They were not even aware that (he) had gone to the Super Bowl."

The former director handed over his company cellphone when he resigned last Tuesday, the person said, and made no mention of the jersey case.

No arrests had been made as of late Monday. The Associated Press is not identifying the director because he has not been charged.

Brady, in a statement emailed to the AP from his agent, Don Yee, expressed gratitude to investigators but said he hadn't yet been reunited with the jerseys.

"I am happy my jerseys from SB 49 and SB 51 have been recovered, and I want to thank all of the law enforcement agencies involved," Brady said. "I know they worked hard on this case - and it is very much appreciated. Hopefully when I get the jerseys back I can make something very positive come from this experience."

Houston police Chief Art Acevedo proudly congratulated his team, but was equally quick to say finding the jersey wasn't a "top priority" in a city with violent crime. He described the theft as the only blemish on an otherwise successful Super Bowl.

"You don't come to Texas and embarrass us here on our home turf," Acevedo said.

A Patriots spokeswoman said the team had no comment.

The jerseys are in the possession of the NFL and FBI in Boston, and law enforcement was working to authenticate them, the chief said.

"We are highly confident that these are the jerseys," Acevedo said.
